Brad Fitzpatrick	9f930ef2bf	wgengine/magicsock: remove the discoEndpoint.timers map It ended up being more complicated than it was worth.	4 years ago
Brad Fitzpatrick	f5f3885b5b	wgengine/magicsock: bunch of misc discovery path cleanups * fix tailscale status for peers using discovery * as part of that, pull out disco address selection into reusable and testable discoEndpoint.addrForSendLocked * truncate ping/pong logged hex txids in half to eliminate noise * move a bunch of random time constants into named constants with docs * track a history of per-endpoint pong replies for future use & status display * add "send" and " got" prefix to discovery message logging immediately before the frame type so it's easier to read than searching for the "<-" or "->" arrows earlier in the line; but keep those as the more reasily machine readable part for later.

Brad Fitzpatrick	7883e5c5e7	go.mod: restore staticcheck module, make it stick around, go mod tidy It kept coming & going as different people ran go mod tidy and others ran staticcheck. Make it stop going away with go mod tidy by adding a dep to it.	4 years ago

David Anderson	73db7e99ab	tstest/natlab: make Machine constructible directly. This is a prelude to adding more fields, which would otherwise become more unnamed function params. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

David Anderson	9cd4e65191	smallzstd: new package that constructs zstd small encoders/decoders. It's just a config wrapper that passes "use less memory at the expense of compression" parameters by default, so that we don't accidentally construct resource-hungry (de)compressors. Also includes a benchmark that measures the memory cost of the small variants vs. the stock variants. The savings are significant on both compressors (~8x less memory) and decompressors (~1.4x less, not including the savings from the significantly smaller window on the compression side - with those savings included it's more like ~140x smaller).

Brad Fitzpatrick	14b4213c17	tstest/natlab: add missing tests from earlier commits Now you can actually see that packet delivery works. Pairing with @danderson	4 years ago

Brad Fitzpatrick	23c93da942	tstest/natlab: start of in-memory network testing package Pairing with @danderson	4 years ago
Brad Fitzpatrick	c52905abaa	wgengine/magicsock: log less on no-op disco route switches Also, renew trustBestAddrUntil even if latency isn't better.	4 years ago
Brad Fitzpatrick	847b6f039b	disco: simplify expression, appease staticcheck Was: disco/disco.go:164:10: unnecessary use of fmt.Sprintf (S1039)	4 years ago
Brad Fitzpatrick	57e8931160	control/controlclient: fix copy/paste-o in debug knob accessor Introduced in `a975e86bb8`. Only affected TS_DEBUG_* env users.	4 years ago
Brad Fitzpatrick	0f0ed3dca0	wgengine/magicsock: clean up discovery logging Updates #483	4 years ago
Brad Fitzpatrick	056fbee4ef	wgengine/magicsock: add TS_DEBUG_OMIT_LOCAL_ADDRS knob to force STUN use only For debugging.	4 years ago
Brad Fitzpatrick	6233fd7ac3	control/controlclient: don't truncate AuthURL in log It's useful to copy/paste directly from there, without using tailscale up. If it's truncated for some specific reason, it doesn't say why.	4 years ago
Brad Fitzpatrick	e03cc2ef57	wgengine/magicsock: populate discoOfAddr upon receiving ping frames Updates #483	4 years ago
Brad Fitzpatrick	275a20f817	wgengine/magicsock: keep discoOfAddr populated, use it for findEndpoint Update the mapping from ip:port to discokey, so when we retrieve a packet from the network, we can find the same conn.Endpoint that we gave to wireguard-go previously, without making it think we've roamed. (We did, but we're not using its roaming.) Updates #483	4 years ago
Brad Fitzpatrick	77e89c4a72	wgengine/magicsock: handle CallMeMaybe discovery mesages Roughly feature complete now. Testing and polish remains. Updates #483	4 years ago
Brad Fitzpatrick	710ee88e94	wgengine/magicsock: add timeout on discovery pings, clean up state Updates #483	4 years ago
Brad Fitzpatrick	77d3ef36f4	wgengine/magicsock: hook up discovery messages, upgrade to LAN works Ping messages now go out somewhat regularly, pong replies are sent, and pong replies are now partially handled enough to upgrade off DERP to LAN. CallMeMaybe packets are sent & received over DERP, but aren't yet handled. That's next (and regular maintenance timers), and then WAN should work. Updates #483	4 years ago
Brad Fitzpatrick	9b8ca219a1	wgengine/magicsock: remove allocs in UDP write, use new netaddr.PutUDPAddr The allocs were only introduced yesterday with a TODO. Now they're gone again.	4 years ago
Brad Fitzpatrick	7b3c0bb7f6	wgengine/magicsock: fix crash reading DERP packet Starting at yesterday's `e96f22e560` (convering some UDPAddrs to IPPorts), Conn.ReceiveIPv4 could return a nil addr, which would make its way through wireguard-go and blow up later. The DERP read path wasn't initializing the addr result parameter any more, and wgRecvAddr wasn't checking it either. Fixes #515	4 years ago
Brad Fitzpatrick	47b4a19786	wgengine/magicsock: use netaddr.ParseIPPort instead of net.ResolveUDPAddr	4 years ago
Brad Fitzpatrick	f7124c7f06	wgengine/magicsock: start of discoEndpoint state tracking Updates #483	4 years ago
Brad Fitzpatrick	92252b0988	wgengine/magicsock: add a little LRU cache for netaddr.IPPort lookups And while plumbing, a bit of discovery work I'll need: the endpointOfAddr map to map from validated paths to the discoEndpoint. Not being populated yet. Updates #483	4 years ago
Brad Fitzpatrick	2d6e84e19e	net/netcheck, wgengine/magicsock: replace more UDPAddr with netaddr.IPPort	4 years ago
Brad Fitzpatrick	9070aacdee	wgengine/magicsock: minor comments & logging & TODO changes	4 years ago
Brad Fitzpatrick	e96f22e560	wgengine/magicsock: start handling disco message, use netaddr.IPPort more Updates #483	4 years ago
Brad Fitzpatrick	790ef2bc5f	internal/deepprint: update copyright header to appease license checker script Plus mention that it's not an exact copy.	4 years ago
Brad Fitzpatrick	eb4eb34f37	disco: new package for parsing & marshaling discovery messages Updates #483	4 years ago
Brad Fitzpatrick	7ca911a5c6	internal/deepprint: add missing copyright headers	4 years ago
Brad Fitzpatrick	a83ca9e734	wgengine/magicsock: cache precomputed nacl/box shared keys Updates #483	4 years ago
Brad Fitzpatrick	a975e86bb8	wgengine/magicsock: add new endpoint type used for discovery-supporting peers This adds a new magicsock endpoint type only used when both sides support discovery (that is, are advertising a discovery key). Otherwise the old code is used. So far the new code only communicates over DERP as proof that the new code paths are wired up. None of the actually discovery messaging is implemented yet. Support for discovery (generating and advertising a key) are still behind an environment variable for now. Updates #483	4 years ago
Brad Fitzpatrick	72bfea2ece	control/controlclient: remove IPv6 opt-out environment variable It was temporary and 3 months has elapsed without problems.	4 years ago
Brad Fitzpatrick	6f73f2c15a	wgengine, internal/deepprint: replace UAPI usage as hash func; add deepprint The new deepprint package just walks a Go data structure and writes to an io.Writer. It's not pretty like go-spew, etc. We then use it to replace the use of UAPI (which we have a TODO to remove) to generate signatures of data structures to detect whether anything changed (without retaining the old copy). This was necessary because the UAPI conversion ends up trying to do DNS lookups which an upcoming change depends on not happening.	4 years ago
Brad Fitzpatrick	103c06cc68	wgengine/magicsock: open discovery naclbox messages from known peers And track known peers. Doesn't yet do anything with the messages. (nor does it send any yet) Start of docs on the message format. More will come in subsequent changes. Updates #483	4 years ago
